HENRY SCI-ILAGHTER, F. BEATRICE, NEBRASKA, ASSIGNOR TO DEMPSTER MANUFACTURING 00., OF BEATRICE NEBRASKAyACORPQRATION OF NEBRASKA.

WINDMILL.

To all whom it may concern:

Be it known that I, HENRY SGHLAOHTER, a citizen of the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented new and useful. Improvements in Windmills, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part 'of this specification.

My invention relates to windmills.

One of the objects of my invention is to provide an improved oiling system for windmills, whereby all of the frictional parts-will be thoroughly automatically lubricated.

Further objects will appear from theldetailed description to follow and from the appended claims.

In the drawings in which an embodiment of my invention is shown Fig. 1 is a top'plan view showing the main frame with an oil reservoir, part of the wind-wheel and transmission between the wind-wheel and'pump-rod, the cover for the oil receptacle being removed;

Fig. 2 is a vertical sectional view along the line 22 of Fig. 1;

Fig. 3 is a section substantially on the line 33 of Fig. 1;

Fig. 4c is an enlarged plan view of the rocker-arm Fig. 5 is a sectional view showing the oil dipper;

Fig. 6 is a section on the line 6-6 of Fig. 2, showing the main crank-shaft bearing;

Fig. 7 is a plan view of the lower half of the outer crank-shaft bearing; and

Fig. 8 is a perspective view of the'lower half of theouter bearing showing the means for scraping the oil from the shaft.

The construction shown in the drawings comprises a wind-wheel 10, (the hub alone being shown) a pump rod'll, transmission 12 between the wind-wheel 10 and'pumprod '11, and a main frame 13 for supporting the wind-wheel 10 and transmission, 12, and for 'aflording a suitable oil reservoir for supplying oil to the transmission 12.

In the particular construction shown a vane 14: is provided for causing the wind wheel 10 to be presented in" proper ,position with respect to the'direction ofjthe'wind, although my invention is applicable to vaneless wind-mills.

The transmission .12 -comprisesa cranlc shaft 15 Ion which the. wind-wheel 10 -is mounted, .a ipitman 16 (Fig. having. one end connected to "the crank Eportion-o-f the cranksshaft 15, .a ,rocker arm -17 to which the Otherend of the connec'ting rod .16 is pivoted, and a pair of lift-rods 1,8 having their lower ends pivotally connected "tothe ro'okerarm 17, and 'theirlupperreiids secured to the pump-rod 11. The rocker-armwis pivotally l mounted onv .a pin =19. The upper ends of the lift-rods 18 are rigidly secured to the-pump-rod 11 by means of :bolts.20. This rigid connection here is permissible because the motionof thelift-rods .18 is so nearly rectilinear that a v pivotal connection betweenthe liftsrods and pumprofd is not necessary. I

As previously intimated, the main frame 13 "providesan oil vreservoirfor oiling the transmission. The frictional parts which. are'oiledfrom this reservoirare as follows: The main bearing for the. crank-shaft .at 21; the outerbearing for the crank-shaft lat 22; thejinner bearing for the crankshaftuatf23; the pivotal connection between the crankshaft and the connecting ,rod at .23, :the pivotal connection between thefconnecting rod and the rocker-M11117 at 24;-.the pivotal mountingof the rocker-arm at 19; and :the pivotal connection between the rocker-arm and the lift rods at 25. The oil level in the reservoir may vary from about the upper line indicated at A to the lower line indicated at B. If-theoil reservoir is-quiteffull the frictional parts at 19, 24: and 25 will be practically immersed inthe oil. The frictional parts at 2'1, 22, .23 and aaearesu plied-with oil dipped up from the reservoir by meansofa revolving dipper 26 (Fig. '5'). The dipper 2,6 scoops up thezoilijfrom the oil reservoirand delivers it to an oil receptacle 27.from whence it flows alongt'heshaft15 to the outer bearing 22, and 'thenoeback to the reservoir, wOil also drains nomfaegreceptacle .27 along :the 'fcrank ,p'orti'on er lithe Qrankj-shaft to the cmalepi 23 and fol: lows along the erank'tdjthe inner "bearings-a,

the line of flow of the oil dipped up by the dipper 26 being indicated diagrammatically by the arrow lines C and D.

The construction is also made such that even when the oil level drops as far as the level indicated at B (which is below the pivot-pin 19 and the lowest portion of the path of travel of the dipper 26) all of the frictional parts referred to will still be supplied with oil. The frictional. parts at 24 and 25 will still dip into' the oil at the lower part of their travel, and the rocker-arm 17 is provided with channels 28 in its upper portion, which. receive oil when the rocker-arm is in its lowermost position, and deliver the oil thus received to the pin 19 when the rocker-arm is in its raised position, the oil flowing downwardly along these channels, and being delivered to an opening 29 (Figs. 3 and 4) in the hub of the rocker-arm and thus'reaching the pivot pin.

In order that the dipper 26 may still be supplied with oil veven when the oil level is low, an auxiliary oil pocket 30 is provided (Fig. 3) into which the dipper 26 dips, this auxiliary oil pocket 30 being kept supplied with oil splashed up by the rocker-arm 17.

I will now describe in detail the circulation of the oil from the oil receptacle 27 to the bearings 21 and 22. and thence back to the oil reservoir. In order to provide for the flow of oil fronrthe receptacle27 (to which it is delivered from the dipper 26) along the shaft 15 to the outer bearing 22, the cap 31 for the bearings 21 and 22 (Figs. 2 and 6) is provided with a channel 32. along which the oil flows to the outer bearing 22. The oil is confined in the channel 32 by the crankshaft 15 so that it is compelled to flow along the shaft to the outer hearing. In order to assist the oil in its travel along this channel, a floating bar 33 may be provided, located in the channel 32. and resting on the shaft 15.

This bar may be of woodQand rests lightly on the shaft, and assists the oil in traveling along the shaft, also tending to prevent the oil from being carried around with the shaft.

In order to return the oil from the bearing 22 to the oil reservoir, an inclined channel 34 is provided in the main frame- 13. this channel running underneath both of the bearings 21 and 22. and serving to drain the oil back into the oil reservoir.

In order to prevent oil from escaping at the outer end of the bearing 22, the lower bearing member 35 is provided with a scraper portion 36, of substantially V-shape,

which scrapes the oil from the shaft 15. at this point, and the oil thus scraped off, drops down into the channel 34 and flows back into the reservoir. p

In further explanation of the drawings. it

" is stated that a brake 37 is provided for the wind-wheel 10 which is automatically applied when the wind-wheel is thrownout of gear. This construction, however, forms no part of my present invention, but is shown and mentioned simply for the sake of com pleteness. 1

An extra connection between the rocker arm 17 and connecting pitman 16 is provided at 38, which may be used in case the load on the mill is too great to use the connection at 24.

A cover 39 is provided for the oil reservoir, which cover may be of sheet metal, h aving a sort of hinged connection at 40 with the reservoir, and having a detachable connection at 41 with the oil reservoir, which can be readily released to allow the cover to be swung upwardly about the pivot at 40. The detachable connection at 41 may comprise an eye-bolt 42, connected at 43 to the cover, and lying in a slotted lug 44, formed integral with the main frame casting. To release, the nut 45 is loosened, the eye-bolt 42 is swung outwardly to free it from the slotted lug 44, and the cover can then be tilted up to afford access to the oil reservoir and the mechanism therein. It will be noted that the pump-rod 11 operates through a sort of tubular passage way 46 extending up to and partitioned off from the oil reservoir, and that the arms of the rocker 17 straddle this tubular passage way, so that the arms 18 will lie in substantially vertical position parallel to they pump-rod 11, so as to lift directly upward on the pump-rod. l I
